Description:

The posix_spawnattr_setsigmask() function sets the
signal mask attribute in an initialized attributes object referenced by attrp.
You must have already initialized the spawn attributes object by calling
posix_spawnattr_init().

The value of this attribute is used as the signal mask in the new process image of a spawn operation if
POSIX_SPAWN_SETSIGMASK is set in the spawn flags attribute;
to set this flag, call the POSIX function
posix_spawnattr_setflags(),
or the QNX Neutrino function
posix_spawnattr_setxflags().
By default, the mask is an empty signal set.
